The setup
Owner Lena fans info@ out to eight tutors plus herself. Tutors are mostly part-time, several change each term.
How the mail flows
- A parent cancels the 5pm slot at 3:40pm.
- Tutor and owner both hold the identical message within minutes.
- The freed slot gets offered to the waitlist instead of sitting empty.
- info@ keeps the billing-relevant record of who cancelled when.
Why Sinka fits here
- Part-timer churn is painless: add an address in September, revoke it in June.
- Tutors reply as themselves, so parents learn a name, not a rota.
- Schedule-change threads stay with the tutor who teaches that child.
Watch out for
- Parents will favourite the tutor who replies fastest; route billing questions back to the owner explicitly.
- Term-time volume spikes copy fine — the batch limit keeps big backlogs draining steadily.
